PAVEMENT RESURFACER.

Application led August 11, 1924. Serial No. 731,340.

This invention resides in the provision of an improved apparatus forre-surfacing and repairing asphalt and bitumen pavements and streets bythe application of heat thereto, said apparatus being simple andinexpensive as to constructionsmall and compact tothe extent that it maybe readily incor'porated with the ordinary motor truck,

capable of being handled and moved with the ease and facility of theordinary motor truck and yet capable of effectively treating acomparatively large area of pavement in a short period of time. i l

One of the objects of the invention is to provide a portable surfaceheater in which a comparatively large heater or furnace may be employedwithout rendering the truck any the less mobile, there being a novel andadvantageous means for mounting and manipulating the furnace to cause itto be moved into the desired position for operation or into position tobe conveniently supported on the truck body.

With the above mentioned and other objects in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed, illustrated in the acv companying drawings, and set forth inthe claims hereto appended, it being understood that various changes inthe form, proportion, size and minor details of construction Within thescope of the claims may be resorted to without departing from the spiritor sacrificing any of the advantages of the invention.

Referring to the drawings:

The figure represents a side elevation of the apparatus of the inventionas when incorporated with a motor truck, the furnace beingshown indotted lines as when supported by the truck.

In the embodiment of the invention shown in the accompanying drawings,the furnace or heater designated A, is mounted on a motor truckdesignated B, and is operated by means generally designated C, in orderthat it may be raised from and lowered into positiony of use andlikewise moved into and out of operative position, in the latter case,so as to be supported on the body of the truck.

The heater or furnace A is provided on its upper side with a bridlel,having a pulley 2 attached to it. A similar pulley 3 depends from acarriage 4, which rides on a horizontal track 5 supported by standards 6and 7 secured to cross pieces 8, which cross pieces support the furnacewhen the latter is in out suitable hoist engine 14. mounted on the truckbody.

By pulling on the fall line 10, the tackle lines 8 operatev to lift thefurnace or heater A, until the blocks close up on one another, afterwhich said line will move the carriage inward on the track 5. Whenmoving the carriage 4 along the track, the furnace is turned lengthwiseof the motor truck in position shown in dotted lines, Fig. 1, and may beallowed to come to rest on the crosspieces 8, between the standards 6and 7 The comparatively long furnace A is turned lengthwise so that itywill not project outwardly from the sides of the truck but will extendslightly rearwardly therefrom instead. Thus, it will be seen that acomparatively large furnace may be used without making the apparatusclumsy or bulky and interfering with the operation of the truck in heavytraffic, or in narrow streets, ete.

Mounted on the body of the truck is a compressed air tank 15 suppliedwith air from the compressor 16 operated by the engine 14. Fuel tanks 17are supported on the body and feed fuel to burners 18 of the furnacethrough a pipe line 19, including a flexible pipe 20. y

The furnace A comprises a shell of rectilinear outline, made up of sheetmetal.

The surface heater of this invention constructed as illustrated andhereinbefore described, is capable of being readily moved from place toplace and when it is desired to ut the furnace in operation, it is runout on the track 5, turned around into position shown in full lines inthe figure, and then lowered by the tackle., into ground engagingposition. The operation of the furnace comprises manipulation of theburners 18 as is customary in the art, and application of the heat tothe surface -of the pavellO ment. The particular manner of mounting thefurnace provides for ready adjustment and movement of the furnace to thedesired position or angle While the vehicle or truck is stationary, andalso facilitates the manip ulation of the truck to move the furnace fromplace to place.

We claim:

l. The combination with a vehicle, of a pavement surface heater furnace,the length of which is greater than the width of the vehicle, a fuelsupply on the vehicle, a fleXin ble fuel feed connection between thefurnace and said supply, means on the vehicle with which said furnace isrotatably connected and by which the furnace is subject to movement in ahorizontal plane through at least 90 of are, which means provides formoving the furnace from position of use into position of rest lyinglengthwise of the vehiclerand from position of rest into position ply onthe vehicle, a flexible fuel feed connection between the supply andfurnace, said furnace being of greater length than the width of thevehicle, a cradle on the vehicle adapted to support the furnace when thelatter is in a. position extending lengthwise of the vehicle, a tracksupported by the vehicle and extending rearwardly thereof, a carriagemovable back and forth on the track and means of connection between thecarriage, furnace and vehicle providing for rotation of the furnace in ahorizontal plane and for movement of the furnace from position of useinto position of rest in engagement with the cradle and vice versa.
